So I had researched it a while ago and don’t recall having found anything effective and non-suspicious to protect from public camera mass survaillence in cities and the like. Is there anything that is a good option for that yet, and if so, could you point me toward it?
Yes, it is dangerous even the reflections off the camera could be dangerous. This requires the same awareness of others as handling a laser cleaner.
Here is an article about using a pulse laser to blind a camera sensor
